Using an ETL Framework vs Writing Yet Another ETL Script

The article discusses how a simple ETL (Extract, Transform, Load) script can evolve into a more complex project as it becomes production-ready. It highlights the need for scheduling, monitoring, debugging capabilities and handling API changes in an ETL script. The author shares their experience of watching this narrative unfold in multiple high-performance engineering organizations. They emphasize that using an ETL framework can provide built-in connectors to extract and load data, common transformation logic, scheduling, monitoring and a better developer experience. Airbyte is mentioned as an open-source ETL framework that helps users avoid the "little ETL script" antipattern by making it easy to write source and destination connectors using their Connector Development Kit (CDK) or ETL framework in Java, Python, C# or JavaScript. The CDK provides improved developer experience and abstracts away low-level glue boilerplate. The author believes that an OSS approach is the only way to solve the problems of data integration as it allows for continuous improvement and support from a community rather than relying on a single company.
